Why can't I change the type of an input elemen

Question

I'm calling this function:

function submit_button(button_id){
    $('#' + button_id).attr('type', 'submit');
}

to make this button type = submit instead of button.:

<input  name="confirm_button" id="confirm_button" type="button" value="Confirm" class="login_btn" />

and I get this error (in firefox):

uncaught exception: type property can't be changed

Are there any work arounds?

Answer 1

function submit_button(button_id){
    $('#' + button_id).prop('type', 'submit');
}

Be aware that this changes the type but not the value, so the button will still read "confirm".

Answer 2

javascript:

function submit_button(){

      var btn=document.getElementById('button_id');
      btn.setAttribute('type', 'submit');

  }

Jquery:

function submit_button(){

 $('#' + button_id).prop('type', 'submit');

   }

Why not just bind to the click event and call the form submit in your click handler?

Answer 4

It worked finally , try finding the following:

   $("#confirm_button").each(function () 
   { this.type = "number"; });

Answer 5

Here's a workaround:

$('<input name="confirm_button" id="confirm_button2" type="submit" value="Confirm" class="login_btn" />').insertAfter('#confirm_button');
$('#confirm_button').remove();

Why jQuery won't allow you to just change the type attribute?

Because it causes problems in Internet Explorer.

More info at: change type of input field with jQuery

"Straight from the jQuery source":

// We can't allow the type property to be changed (since it causes problems in IE)
if ( name == "type" && jQuery.nodeName( elem, "input" ) && elem.parentNode )
    throw "type property can't be changed";
